Create a Segment to Globally Qualify or Suppress Contacts
I work with other ESPs that let you create a segment and specify it as a global filter for every email that gets sent out of the ESP. In other words, the system checks against the filter to determine you're qualified to receive ANY emails, batched or workflow, without having to modify contact status or add additional criteria to every active segment or list.
Use case: When updating segments for GDPR, I had to modify every single segment we use (~20) to exclude contacts with an EU billing address. Having an account-level segment that can be used as a filter would've allowed me to make the change in just one location instead of 20.
